A recent study though, suggests that over five thousand years ago, the Arctic had considerably less sea ice in the summertime than today, but it was not apparent whether the Arctic was totally free of sea ice in the summertime throughout that time.
8) What is the difference between the seasonal patterns of Arctic Ice in comparison to Antarctic Ice?
The model of Antarctic maximum sea ice is generally symmetric around the pole, shaping a circle around Antarctica. On the other hand, the Arctic is asymmetric, with a lot more ice in some longitudes than in others.
9) What is the explanation for these variations?
These variations take place because of the way the currents and winds move. In the Antarctic there are not disruptions...
Geology Describe the paths of water through the hydrologic cycle. Explain the processes and the energy gains and losses involved in the changes of water between its three states. Operationally, we are often most concerned with what water does when it reaches the solid earth, both on the surface and in the sub-surface. Explain the relationship between the saturated zone, the water table, a groundwater well and the cone of depression,
Geology You are watching Friends on TV and Ross, a paleontologist, mentions he found a dinosaur bone that was trapped in lava 120 million years ago. Your little sister asks you how Ross knows that the dinosaur bone is 120 million years old. Answer her question using the information you learned about isotopic dating in this course. Isotopic dating uses radioactive material to date rocks. It generally compares the presence of a
Smith went deep into debt and as creditors chased him, he was unable to enjoy any of the fruits of his labor. Forced to sell off his fossil collection, Smith eventually retreated into Northern England and lived as a pariah. Before he did, he also entered into an unwise marriage with a mentally disturbed woman. Smith was also imprisoned for his debt. Throughout much of his life, Smith received little
Geology Film Rebirth: A Geologically Based, Imaginative Film Today's environmentalists often tell the public about the harmful effects of our actions. Yet, despite warnings of too many carbon emissions from vehicles and deforestation woes, our society does not seem to understand just how harmful our actions can be. However, if we do not take action to alleviate these worrisome actions some way, these warnings will turn into reality, and we might not only
National Park Dry Tortuga National Park Granted that Key West, Florida may be the southernmost indicate in the mainland United States, the story of America's rich customary legacy develops past the zero mile marker of U.S.-1. Found practically 70 miles off Nexus West is a group of seven coral reef islands that pilgrim Ponce de Leon came across in 1513. Upon seeing the bounteous people of ocean turtles, he named the islands
Specific legislation on rights of way would have to be enacted separately in order to apply to any of the other parks (for instance, the 1915 act creating Rocky Mountain National Park contained rights of way). (Winks 1997) Powers Under the Act of 1970 act, Congress proceeded to create new National Recreation Areas, including "urban parks." The act clearly strengthened the Park Service to protect park units in all ways by
